GSM engine (GSM Cellular Engine) and 51 lists due to the HRH embedded high reliability of GSM Modem
Sheet machine system (MCS51), standard serial interface and the software interface agreement simplified by user from numerous and diverse GSM communication standard solution
Analysis and debugging free, easy to use, and also the transmission of the data of public network has communication range, and extensively (GSM network covers substantially
The whole nation), the features such as transmission is stable, reliable.Therefore the design selects HRH GSM Modem to communicate.Its major function is
A. note is received and dispatched;B. the transmission of long-range small lot data is realized by note;C. voice call (GSM phone) d. number arq mode
Realize wireless real time data communication;E. (automatic-answering back device type) is got online without being tethered to a cable.Module require 12V/500mA power, with computer or
Single-chip microcomputer passes through serial communication, baud rate 9600bps, installs SIM by SIM card holder.
In order to send the function of short message when realizing system generation alert to the number specified, then must have keyboard and
LED shows, guard against theft and alarm system is carried out telephone number and presets, and the design selects HD7279 to drive as keyboard & display.
In order to prevent burglar by the supply and AC dump of system before entering defence area, system allows in alternating current power supply
Continuing after Bei Qieduan properly functioning a period of time, native system uses the lead-acid accumulator of 12V/7AH as back-up source, and this just gives
System design proposes a problem continuing to solve: be exactly the charge power supply problem of management of accumulator.
During in order to realize occurring alert, the time that alert occurs is carried out record, and in order to ensure the reliability service of system,
Requirement system carries out self-inspection timing reporting system running status, it is therefore desirable to system has real-time clock function.The design selects
Use DS12887 real-time timepiece chip.
The cloth of system, disarming state can be changed before entering defence area or after leaving defence area to realize user, this
315M amplitude modulation remote controller has been selected in design, and this remote control appliance has the advantage that
1. it is operated in amateur band, need not spend to buy frequency;
2. coverage is remote, typically up to 2001000 meters;
3. there is abundant address code to select for user, due to the PT2262/PT2272 of application on remote controller and remote control plate
The codec chip codec state to all providing 8 tri-states, say, that have the 8 power address codes of 3 to be available for user and select, foot
Burglar alarm cloth, application of withdrawing a garrison with users all in meeting community.
In order to prevent due to accidentalia alternating current power supply power-off, system allows for just continuing after alternating current power supply is cut-off
Often running a period of time, native system uses and arranges back-up source.
The design selects electrochemistry type gas sensor, electrochemistry type gas sensor can be divided into primary cell type, controllable electric
Position electrolytic, electricity quantity type and ion electrode formula four type.Primary cell type gas sensor carrys out detected gas by detection electric current
Volume fraction, the instrument of commercially available detection anoxia is nearly all furnished with this sensor, in recent years, develops again detection sour gas
The primary cell type sensor of body and poisonous gas.The electric current that controlled potential electrolysis formula sensor flows through when being by measuring electrolysis comes
The volume fraction of detected gas, and unlike primary cell type, need to be applied specific voltage by the external world, except detecting
CO, NO, N02,02, outside the gas such as S02, moreover it is possible to the oxysome fraction in detection blood.Electricity quantity type gas sensor is logical
Cross tested gas and electrolyte to react the electric current produced and carry out the volume fraction of detected gas.Ion electrode formula gas sensor occurs
Relatively early must carry out, by measuring ionic polarization electric current, the advantage that the volume fraction electrochemical gas sensor of detected gas is main
Be detected gas highly sensitive, selectivity good.At least can reach following beneficial effect: overcome landline telephone in prior art
Dial by accidentalia cut-out telephone wire or maliciously the line is busy so that it is malfunctioning at crucial moment, Ethernet is faced with circuit quilt equally
The hidden danger cut off, and be difficult to popularize, group system power consumption is very big, and network sets up and maintenance cost is the highest, and needs purchase solid
Fixed frequency, overcomes owing to can not check conventional alarm logging, thus can not make tight arrangement further to deploying troops on garrison duty.Keep away
Exempt from potential safety hazard, be independent of telephone and perform warning, and by the most reliably, the most ripe GSM mobile network, with the most intuitively
Chinese short message or telephony modalities, directly reflects the situation in warning place on mobile phone screen, allow antitheft more in time, use more
Convenient.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
